In an Islamist grievance culture, the tower doesn't have to be that tall to loom. The tragedy in Wright's book is that across little more than half a century a loser cult has metastasized, eventually to swallow almost all the moderate, syncretic forms of Islam. What was so awful about Sayyid Qutb's experience in America that led him to regard modernity as an abomination? Well, he went to a dance in Greeley, Colo.: "The room convulsed with the feverish music from the gramophone. Dancing naked legs filled the hall, arms draped around the waists, chests met chests, lips met lips . . ."

In 1949, Greeley, Colo., was dry. The dance was a church social. The feverish music was Frank Loesser's charm song Baby, It's Cold Outside. But it was enough to start a chain that led from Qutb to Zawahiri in Egypt to bin Laden in Saudi Arabia to the mullahs in Iran to the man arrested in Afghanistan on Sept. 11. And it's a useful reminder of how much we could give up and still be found decadent and disgusting by the Islamists. A world without Baby, It's Cold Outside will be very cold indeed.

We should realize that peace on the Islamists' terms will not be very pleasant.
